My invention relates to household heating apparatus and particularly to household heating apparatus which may be installed in the walls of houses or other buildings.

The invention has among its other objects the production of apparatus of the kind described, which is compact, convenient, durable, eliloient and which may be installed in v p, buildings alread in existence.

W A further obgect of the invention is the provision of improved apparatus of the kind described which is readily accessible for re- 'pairs and which is easily dismantled and re- N moved for renewal or repairs.

Another object of the invention is the provision of apparatus of the kind described, which may be readily installed in a relatively narrow wall.

V Still another object of the invention is the 2Q provision of apparatus of the kind described,

which may be removed from its mounting without tearing out any portion of the wall in which it is positioned.

Many other objects and advantages of the '25 construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and departs 1F ig. 1 is a fragmentary elevational view of a wall in which apparatus embodying the invention is installed;

Fig. 2 is a section along the line 22 of '40 hi 1; and

Fig. 3 is a section along the line 33 of Fig 2.

eferring to the drawing wherein I have v shown a preferred form of the invention embodied in'apparatus which is installed in a wall or partition forming part of a dwelling or other building, the wall being generally designated by the numeral 10, is of any type commonly employed in dwellings and other 5 buildings of a similar character.

The wall 10 is shown as comprising stud ding 11, spaced apart to permit a duct 12 to be positioned therebetween. The studding may be covered by any suitable material such as plaster, plaster board, or the equivalent, as indicated at 13. Upper and lower apertures 1d and 15, respectively, being formed in the wall 10 to provide discharge outlet and inlet openings, respectively. The duct 12 has vertically extending end walls 16 connected by front and rear walls 17 and 18, respectively.

The rear wall 18 has its upper portion turned outwardly with its end terminating in alignment with the surface of the wall 13. The upper end of the front wall section 17 is also turned outwardlyterminating in the face of the plaster wall 13, the horizontal portions of the walls 17 and 18 together forming the upper and lower boundaries'of the aperture 1 1. The lower end of the front wall section 17 terminates at the upper edge of the aperture 15. The lower end of the rear wall section 18 terminates at considerable distance below the corresponding terminus of the front wall section 17. if desired, the rear wall section 18 will extend to the floor.

A radiator unit 20 is positioned in the duct 12 preferably immediately above the aperture 15. The radiator unit 20 comprises a plurality of horizontally extending tubes 21 which connect header tanks 22 oppositely positioned in the duct 12. The tubes 21 are of relatively narrow construction and are placed side by side to form a thin radiator unit, thenumber of tubes being varied to suit the thickness of the wall in which the duct 12 is positioned. A plurality of transversely extending fins 23 are mounted on the tubes 22 to accelerate the transfer of'heat from the radiator unit 20 to the column of air ascending through the duct 12.

The radiator unit 20 is supplied with heating fluid through a main pipe 26. The flow of heating fluid to the radiator unit is controlled by a valve 27 which is connected with a union 28 by means of a nipple 29. A. nipple 30 connects the union with an i. 31. A vertically extending pipe section 32 connects the L 31 with the radiator unit 10. The valve radiator unit is positioned above the aper The radiator unit 20 is connected Wltll.

ture. a discharge pipe 38 through the medium of a vertically extending pipe 33. The plpe 33 is positioned opposite to the P k preferably of the same len h. horlzontal pipe is connected wit the pipe 33 by an L 34 and with the discharge pipe 38 through .a union 36 and a steam trap 37. The various Us and unions connecting the main feed pipe 26 and discharge pipe 38 with the radiator unit 20 are positioned adjacent the lower aperture 15 so as to be accessible for detachment for repairs or in-case it is found desirable to remove or replacethe radiator unit 20. The radiator unit 20 can be removed by merely unthreading the pipes 32 and 33 from the Us 31 and 34, respectively, the pipes being preferably of the same length and, for this purpose similarly arranged.

A grille 24 partially closes the upper aperture 14. A grille 25 similarly closes the lower aperture 15. The grille 25 is provided with a hinged connection 26' by means of which the grille may be opened to permit access to the heating device when desired.

Thus it will be seen that I have provided a heat exchange unit adapted to be easily installed in, and removed from, relatively narrow walls, either old or new, and which is so constructed as to be easily accessible for inspection and for repairs. 1

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departin from the spirit of my invention; hencefi do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses mentioned.
